The making of Harry Carter, Typographer

Once the text and other casting instructions have
been keyed and punched onto the paper tape, the tape is read by the caster,
and each letter (and space) is individually cast in a mould of the right size (eg
12pt) which is momentarily capped by the matrix for that letter whilst molten
metal is squirted into the mould. The resulting 'sort' is ejected and pushed
onto its line. When a line is complete it is pushed down the galley making space
for the next. The lines, all correctly justified, build up in the galley which is at bottom
Here we can see the 15*17 array of matrices for the 12D Romulus in its diecase. Each brass matrix forms the printing surface of one letter, a lower case italic e for instance. The diecase actually goes inside the heart of the caster but is shown here sitting near where it is loaded.
